What am I suppose to see there?
Its Chinese system and not South African , again based on pics i may be wrong but does not looks like South African
The question is
'Is Chinese system/probe compatible with Russian pods in PAF IL78 or pods are also being updated with Chinese system which is NATO compliant RDC-1
China's tanker conversion was the result of an MoU signed with FRL Ltd in the UK, in 1986. The result of this effort was an adaptation of the H-6 design with two indigenous pylon mounted RDC-1 hose/drogue pods resembling older
FRL Mk.32 pods, these pods were designed by the China Research Institute of Aero Accessories.
The valves in the probe and drogue that are most commonly used are to a
NATO standard and were originally developed by the company
Flight Refuelling Limited in the UK and deployed in the late 1940s and 1950s[

This is so that if a large side or vertical load develops while in contact with the drogue, the rivets shear and the fuel valve breaks off, rather than the probe or receiver aircraft suffering structural damage. A so-called "broken probe" (actually a broken fuel valve, as described above) may happen if poor flying technique is used by the receiver pilot, or in turbulence[
